The B7057 is a short link road in north Lanarkshire.
Shotts Road
The route starts in a forest at a TOTSO on the B717 and heads north, signposted to Glasgow and Edinburgh. It follows the largely straight Shotts Road across poor-quality fields and presently reaches the B7066, which is crossed via a right-left staggered crossroads. Continuing north, the route soon splits into the sliproads for the M8 as J5. This is a modified Trumpet Interchange, with additional turns permitted (via lightly used sliproads) to access the farm on the north side of the motorway. Motorway regulations therefore start later than would normally be expected.
History
The route was originally unclassified but had gained its number by 1932. What is now the B7066 was originally an unclassified road, and the B7057 continued straight across and soon ended at a T junction on the A705 (renumbered A8 in 1935). The new interchange was built in c1966 when the old A8 was upgraded to dual carriageway and became the M8 motorway. This saw the northern end of the B7057 rebuilt on a new alignment slightly further east than it used to run, with the old road still partially visible leading away from the B7066 at the junction.
